Description
Technical Field
The invention relates to the technical field of boiled pulp separation, in particular to a separation method of boiled pulp of a separation type pulping machine.
Background
The bean products (bean curd, bean curd strips, fermented bean, soybean milk, fermented soya beans, soy sauce, bean sprouts, bean intestines, bean tendons, bean fish, lamb tripe strips, cat ears, vegetarian chicken wings, soybean ears and other delicious foods) are mostly bean curd made of soybean milk coagulated noodles of soybeans and reproduced products thereof. The first step of producing bean products is soaking soybeans, the second step is grinding the soybeans into milk, the third step is separating milk residues, the milk residues are separated into soybean milk and bean residues, and then the soybean milk can be coagulated to produce various bean products. The most important link for producing the bean products is the separation of pulp and slag, the clean yield of the pulp and slag separation is high, and the unclean yield is low.
The conventional domestic cooked milk separation methods of the milk mills are various, and the analysis is that the common method is to separate liquid from solid particles by a centrifugal force through a centrifugal milk-residue separator and a common milk-residue separator, and the process flow of separating the soybean milk by the centrifugal milk-residue separator comprises material soaking, milk grinding, separation, re-separation and three separation; the general pulp-residue separator has the same procedures as a centrifugal pulp-residue separator, and has the difference that the yield is less than that of the centrifugal separator, the production scale is not large, the pulp-residue separator is suitable for small workshop production, and the other steps are the same and are not explained in detail.
The existing boiled pulp separator: the cooked soybean milk process mainly adopts a one-time extrusion mode of equipment to complete the separation of soybean milk and residues, and comprises the processes of material soaking, soybean milk grinding, soybean milk residue boiling and soybean milk residue separation, the soybean products made by the process are more elastic, the extraction temperature of the cooked soybean milk process is higher, the nutrient substances are easier to extract, the extraction rate of the cooked soybean milk process is about 10 percent higher than that of the raw soybean milk process, and the soybean milk of the cooked soybean milk process exceeds the soybean milk of the raw soybean milk process in the production processes of the old bean curd, the dried bean curd and the beancurd. The soybean milk with the same concentration of 11Bx and the same amount is used for processing the old bean curd, the yield of the bean curd made by the soybean milk in the cooked soybean milk process is 5-10% higher than that in the raw soybean milk process, and the elasticity of the bean curd is better. The boiled pulp process has great advantages in the aspects of water retention property, tissue structure extensibility and the like, but the equipment is too high in cost, domestic extrusion equipment is still difficult to control temporarily, and the Japanese equipment is too expensive.
